Function documentation

AliFlowVector()
 default constructor
AliFlowVector(const AliFlowVector& aVector)
 copy constructor
AliFlowVector(Double_t* y, Double_t m = 1, Int_t h = 2, Int_t poiType = 0, Int_t s = -1)
 Analogue of TVector2 constructor. Sets (x,y) and multiplicity 1.
AliFlowVector(const TVector2& p, Double_t m, Int_t h = 2, Int_t poiType = 0, Int_t s = 1)
 custom constructor, Sets vector and multiplicity
AliFlowVector(Double_t x, Double_t y, Double_t m = 1, Int_t h = 2, Int_t poiType = 0, Int_t s = -1)
 custom constructor analogue of TVector2 constructor
~AliFlowVector()
 default destructor
void SetMagPhi(Double_t size, Double_t angle, Double_t mult = 1)
 Analogue to SetMagPhi for a TVector2 but here including a sum of weights
AliFlowVector& operator=(const AliFlowVector& aVector)
 assignement operator
AliFlowVector& operator+=(const AliFlowVector& aVector)
 addition operator
AliFlowVector& operator-=(const AliFlowVector& aVector)
 subtraction operator
AliFlowVector& operator*=(Double_t w)
 multiply by a weight operator
void Clear(Option_t* option = "")
clear
Int_t SubtractTrackWithDaughters(const AliFlowTrackSimple* track, Double_t extraWeight = 1.)
subtract a track and all its daughters, only if tagged with flowTag and in specified
subevent (-1 for no subevent selection)
to only subtract if it was actually used in the construction of the vector)
TODO: maybe make recursive if it ever becomes needed
for complicated decay topologies
